SIDE-HEAD TOOL-HOLDER FOR METAL-PLANERS.

Patented Oct. 19, 1909.

Serial No. 451,754.

To all whom it may concern:

Be it known that we, CHARLES MEIER and GEORGE LANGEN, citizens of theUnited States, residing at Cincinnati, Ohio, have invented new anduseful Improvements in Side-Head Tool-Holders for Metal-Planers, ofwhich the following is a specification.

Our invention relates to an improvement in metal planers andparticularly to an improved clamp for a hinged tool holder.

The object of the invention is to provide an adjustably yielding andconveniently manipulated clamp especially adapted for such tool holderwhen mounted on a sidehead. This object is attained in the followingdescribed manner as illustrated in the accompanying drawings, in whichFigure 1 is a side elevation with parts broken away of a metal workingplaner embodying our improvements; Fig. 2, a front elevation with partsbroken away; Fig. 3 a bottom view with parts broken away, and parts insection, and Fig. 4 a transverse section on the line aa of Fig. 2.

In the drawings, 1 represents the bed of a metal working planer, 2 thetable, 4 one of the shifting dogs thereon, 7 the housing, 8 the sidehead adjustable thereon, and provided with a hinged tool holder 9, allbeing constructed and arranged in the ordinary manner except ashereinafter described.

The tool holder 9 hinged on member 19 of the side head 8 in the usualmanner is maintained in the closed position under a yielding pressure bymeans of the engagement therewith of the projecting lip 21 formed on thehead of the clamping bolt 22. Said bolt is provided with a nut 23 foradjusting the coiled spring 24 thereon within the counter bore 25 formedin the edge of member 19. A handle 26 projects laterally from the headof said bolt for convenience of access in turning the bolt with lip 21out of engagement with the edge of the tool holder that it may be turnedin an outward direction, as shown in Fig. 3, when desired for sharpeningthe tool or for other purposes.

In operation, the position of the handle on the clamping bolt isconveniently accessible to the operator especially when a tool isclamped in position on the tool holder.

Having fully described our improvements, what we claim as our inventionand desire to secure by Letters Patent of the United States is 1. In aplaner, the combination of a sidehead, a tool holder hinged thereto, aclamping member in the side-head and adapted to move transverselythereof, a handle whereby said member may be rotated out of and intoengagement with the tool holder, and a spring for maintaining saidclamping member in yielding engagement with said tool holder.

2. In a planer, the combination with a side-head, of a tool holderhinged thereon, a clamping bolt provided with a lip for engaging thetool holder and retaining it in place, a spring arranged to maintainsaid lip in such engagement under a predetermined yielding pressure, anda handle on said bolt for turning said lip out of and into yieldingengagement with the tool holder.

8. In a planer, the combination with a side-head having a countersunkbolt hole therethrough, a tool holder hinged to the side-head, a boltlocated in said hole and having a lip for engaging the tool holder toretain it in place, a spring about the bolt in the countersink, a nut onsaid bolt for adjusting the tension of said spring, and a handle to saidbolt for swinging said lip out of and into engagement with the toolholder.-

CHARLES MEIER. GEORGE LANGEN.
